Deploy Neutron in an MCT Network

About this task

This procedure provides steps to deploy Neutron in an MCT network with the following connections:

Compute Host Compute-1: Network interface card eth1 and eth2 connected to switch Leaf-1 port 0/1 and switch Leaf-2 0/1(MCT pair)
Compute Host Compute-2: Network interface card eth1 and eth2 connected to switch Leaf-3 port 0/1 and switch Leaf-4 0/1(MCT pair)

Note

All network and server connection settings and mappings can be saved to csv files for bulk configuration using the startup file option in the ml2_conf_extreme.ini file.

Procedure

Log in to the network node using SSH and go to the EFA folder.
```
# cd efa
```
Add the ovs bond at compute-1 and compute-2 using 802.3 ad.
```
# sudo ovs-vsctl add-bond br0 bond0 eth1 eth2 lacp=active
```

Build the topology.

# sudo efa-pn-mapping add -H compute-1 -p physnet1 -n eth1 
# sudo efa-pn-mapping add -H compute-1 -p physnet1 -n eth2 
# sudo efa-pn-mapping add -H compute-2 -p physnet1 -n eth1 
# sudo efa-pn-mapping add -H compute-2 -p physnet1 -n eth2 

# sudo efa-link-mapping add -H compute-1 -n eth1 -s leaf-1-ip-address -p 0/1 -P lag_compute1 
# sudo efa-link-mapping add -H compute-1 -n eth2 -s leaf-2-ip-address -p 0/1 -P lag_compute1 
# sudo efa-link-mapping add -H compute-2 -n eth1 -s leaf-3-ip-address -p 0/1 -P lag_compute2 
# sudo efa-link-mapping add -H compute-2 -n eth2 -s leaf-4-ip-address -p 0/1 -P lag_compute2

These configurations can be included in pn.csv and link.csv files for bulk topology setup.

Create the Neutron network and subnet.

# openStack network create GREEN_NETWORK --provider-network-type vlan --provider-physical-network physnet1 --provider-segment 2000

# openstack subnet create subnet1 --network GREEN_NETWORK --subnet-range 20.0.5.0/24

Create a Neutron port.

# openstack port create port0 --network GREEN_NETWORK

Create a VM.

# openstack server create --flavor m1.tiny --image cirros-0.3.5-x86_64-disk --nic port-id=port0 --availability-zone compute-1 instance-1
